1Operational amplifier — A Signetics μa741 operational amplifier, one of the most successful op amps. An operational amplifier ( op amp ) is a DC coupled high gain electronic voltage amplifier with a differential input and, usually, a single ended output.[1] An op amp… …
2Electronic amplifier — A practical amplifier circuit An electronic amplifier is a device for increasing the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. In… …
3Buffer amplifier — A buffer amplifier (sometimes simply called a buffer) is one that provides electrical impedance transformation from one circuit to another. Two main types of buffer exist: the voltage buffer and the current buffer. Figure 1: Top: Ideal voltage… …
4Differential amplifier — symbol The inverting and non inverting inputs are distinguished by − and + symbols (respectively) placed in the amplifier triangle. Vs+ and Vs− are the power supply voltages; they are often omitted from the diagram for simplicity, but of course… …
5Class-D amplifier — Block diagram of a basic switching or PWM (class D) amplifier A class D amplifier or switching amplifier is an electronic amplifier where all power devices (usually MOSFETs) are operated as binary switches. They are either fully on or fully… …
6Distributed amplifier — Distributed amplifiers are circuit designs that incorporate transmission line theory into traditional amplifier design to obtain a larger gain bandwidth product than is realizable by conventional circuits. N stage traveling wave amplifier …
7Variable-gain amplifier — A variable gain or voltage controlled amplifier is an electronic amplifier that varies its gain depending on a control voltage (often abbreviated CV). VCAs have many applications, including audio level compression, synthesizers and amplitude… …
8OCL Amplifier — An OCL amplifier (output capacitor less amplifier) is any audio amplifier with direct coupled capacitorless output. Typically OCL amplifiers can be any of several amplifier classes, and typically have a push pull output stage. Advantages of OCL… …
9Error amplifier (electronics) — An error amplifier is most commonly encountered in feedback unidirectional voltage control circuits where the sampled output voltage of the circuit under control is fed back and compared to a stable reference voltage. Any difference between the… …
